铝合金热处理计算机模拟的一些进展

Development of Computer Modeling for the Heat Treatment of Aluminum Alloys

热处理是控制铝合金性能的重要手段 ,选择最佳热处理工艺参数往往需要进行系统的实验研究 ,经历复杂的筛选优化过程。科学的计算模拟能够大大加速这个过程 ,从而节省物力和时间。同时还能够提供合金热处理过程的精确控制。计算机模拟有两类方法 ,物理法和经验法 ,本文着重讨论物理方法 ,涉及铝合金固溶。

It is time and money consuming process to choose optimum parameters of heat treatment. However complicated experimental work can be substituted by computer modeling and accomplished at greatly accelerated speed. There are two classes of computer modeling which are physical method and empirical method. Physical method is introduced in the present paper and computer simulation for the processes of solution, cooling and ageing is discussed.
